- Does the knob at the end of a telescopic antenna have a significance?
This is probably a trivial or even a stupid question, the reason I am writing here is I couldn't find something satisfactory online. I am a new amateur radio operator. Currently enjoying listening to SW and MW bands. I have a nice radio receiver with a long telescopic antenna. I have noticed that the knobs at the end of telescopic antennas sometimes come in different sizes. Are they there only for ease of handling when increasing the length of antenna or preventing the end from slipping inside? Or do they have a significance in terms of some technical detail like introducing a capacitive load or so?
